Project Gutenberg (PG) is a volunteer effort to digitize and archive cultural works, to "encourage the creation and distribution of eBooks". It was founded in 1971 by Michael S. Hart and is the oldest digital library.Most of the items in its collection are the full texts of public domain books. The project tries to make these as free as possible, in long-lasting, open formats that can be used on almost any computer. It has 50,000 items in its collection.

OpenDOAR is an authoritative directory of academic open access repositories. Each OpenDOAR repository has been visited by project staff to check the information that is recorded here. This in-depth approach does not rely on automated analysis and gives a quality-controlled list of repositories.

Ministry of Human Resource Development under its National Mission on Education through Information and Communication Technology has initiated the National Digital Library (NDL) pilot project to develop a framework of virtual repository of learning resources with a single-window search facility.

This is a collection of public domain and open access documents with a focus on American and English literature as well as Western philosophy. Its purpose is to help facilitate a person's liberal arts education.

It has completely free books from a variety of different authors, collected here for you to read online or offline. The books may have been published before, but not in this form, which I hope you find enjoyable to read and print.

ipl2 is a public service organization and a learning/teaching environment. To date, thousands of students and volunteer library and information science professionals have been involved in answering reference questions for our Ask an ipl2 Librarian service and in designing, building, creating and maintaining the ipl2's collections. It is through the efforts of these students and volunteers that the ipl2 continues to thrive to this day.
